TITLE: LAKE LEVEL MONITORING USING SPACE GEODETIC TECHNOLOGIES 

SPEAKER: C.K. Shum
Laboratory for Space Geodesy and Remote Sensing Research, Department of
Civil and Environmental Engineering and Geodetic Science, The Ohio State
University.

ABSTRACT:Space geodetic measurements are accurate, abundant, all-weather
system, and they are ideally suited to be used as a cost-effective data
source for a number of environmental research and operational studies in
the Great Lakes. Current observations used for environmental monitoring and
coastal forecasting systems are tide gauges and GOES and AVHRR imageries,
which are not all-weather measurement systems. There is also a winter data
outage problem. This paper describes research ongoing using space geodetic
measurements as a complementary data set to the existing data used for
environmental monitoring and Lake Circulation and weather forecasting. The
primary objectives of the investigation is to demonstrate the use of space
geodetic measurements (radar altimeters and GPS-buoys) for improving
temporal and spatial resolutions of measurements for absolute lake
elevation, wave height, wind speed, water vapor and lake ice boundary. The
composite data are to be used to study the potential improvement of the
accuracy in the current operational Great Lakes forecast systems.
Continuous GPS (CGPS) stations are being established around the Great
Lakes, including a proposed location on the Cooke Castle at the F.T. Stone
Laboratory, Lake Erie, for studies including GPS meteorology, crustal
motion, and safe navigation. The development of GPS-buoy water level
instrument for absolute calibration of altimeters in Lake Erie will benefit
global sea level and climate change studies.

TITLE: DIGITALIZATION OF COASTAL ENVIRONMENTAL MONITORING SUPPORTED BY
MULTI-DIMENSIONAL GEOSPATIAL INFORMATION AND ANALYSIS: A DEMONSTRATION 

SPEAKERS: Tarig Ali and Ron Li
Mapping and GIS Laboratory and Laboratory for Space Geodesy and Remote
Sensing Research, Department of Civil and Environmental Engineering and
Geodetic Science, The Ohio State University.

ABSTRACT: This demonstration presents the outcomes of the first year of an
NSF-funded Digital Government project to investigate and develop
technologies to enhance the operational capabilities of federal, state, and
local agencies responsible for coastal management and decision-making. The
objectives of the project are to significantly enhance capabilities for
handling spatio-temporal coastal databases, build a fundamental basis of
coastal geospatial information for inter-governmental agency operations,
and provide innovative tools for all levels of governmental agencies to
increase efficiency and reduce operating costs. The presentation focuses on
the modeling and generation of environmental monitoring of Lake Erie
shoreline changes, including the use of high-resolution IKONOS stereo
images, radar altimetry, water level gauges, using a web-based erosion
awareness system.
